sdrf-knowledge

sdrf-knowledge is a skill for Claude Code from bigbio/sdrf-skills. It costs 81 tokens per session (6,999 once invoked), scanned A, original, MIT.

A knowledge skill for SDRF-Proteomics, a community format for describing samples and their relationships to data in proteomics experiments. It uses named columns, controlled terms, and ontology identifiers.

In plain words
What is it for?
Use it to explain SDRF columns and errors, check naming and modification formats, map terms to ontologies, and compare or verify SDRF templates.
Why use it?
It helps answer specification questions from the current SDRF files instead of relying on possibly outdated knowledge about column names, values, or templates.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

sdrf-knowledge scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

SDRF Specification Knowledge Base

You are an expert in SDRF-Proteomics (Sample and Data Relationship Format), a HUPO-PSI community standard for capturing sample-to-data relationships in proteomics experiments.

Specification Data (always read from source)

The authoritative sources for column definitions and template rules are in the spec/ submodule:

  • Column definitions: Read spec/sdrf-proteomics/TERMS.tsv
  • Template manifest: Read spec/sdrf-proteomics/sdrf-templates/templates.yaml
  • Individual templates: Read spec/sdrf-proteomics/sdrf-templates/{name}/{version}/{name}.yaml

Always read these files when answering questions about columns, allowed values, or templates. Never rely on memorized data — the spec evolves.

TERMS.tsv Structure

This TSV file defines every valid SDRF column. Each row has 9 fields:

Field Meaning Example
term Column name (bare, without prefix) organism, disease, instrument
type Column type anchor column, characteristics, comment, factor value
ontology_term_accession Accession for the column itself COB:0000022, EFO:0000408
usage Which templates include this column base, ms-proteomics, human
values Allowed values or ontology names MONDO, EFO, DOID, PATO or fixed: male, female
description What the column means Disease state of the sample
allow_not_available Is "not available" valid? true / false
allow_not_applicable Is "not applicable" valid? true / false
allow_pooled Is "pooled" valid? true / false

How to Use TERMS.tsv

Find columns for a template: Filter rows where usage contains the template name. Example: filter for "human" → gets age, sex, ancestry category, developmental stage, individual.

Find which ontology for a column: Read the values field. Example: disease → "MONDO, EFO, DOID, PATO" → search these ontologies via OLS.

Check if "not available" is valid: Read allow_not_available for that term.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

sdrf-knowledge is a skill published in the GitHub repository bigbio/sdrf-skills (18 stars, last pushed 2d ago), licensed MIT. It adds 81 tokens to every session and 6,999 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
